Answer:

$a(n) = a(n - 1) - 27$

The nth number is the previous one minus 27.

54 = 81 - 27

27 = 54 - 27

0 = 27 - 27

Angles P and Q are complementary.

GenaCL600 [577]

Answer:

Explained below.

Step-by-step explanation:

Complementary angles are angles that sum up to 90°.

Here,

Angle P = 2x
Angle Q = 7x

Then,

Angle P + Angle Q = 90°

2x + 7x = 90°

9x = 90°

x = 90/9

x = 10°

Therefore,

Measurement of Angle P = 2x = 2*10 = 20°
Measurement of Angle Q = 7x = 7*10 = 70°
